Permatex 81860 is a sensor-safe blue RTV silicone gasket maker in a 7.25 oz. tube. Originally formulated as Permatex No. 6, it now includes a low-odor formula that will not foul oxygen sensors. The compound forms reliable in-place gaskets that resist cracking, shrinking, and migration, and it can also coat pre-cut gaskets to increase sealing reliability. Temperature range is -65°F to 500°F (-54°C to 260°C) intermittent, with resistance to automotive and shop fluids. This OEM-specified sealant replaces almost any cut gasket. Call us to confirm the right formulation for your application.
